# Commission Regulation (EC) No 2870/2000 of 19 December 2000 laying down Community reference methods for the analysis of spirits drinks, Division 8: Calculation

Extent: E+W+S+N.I.

Compare the two chromatograms obtained for the standard solution and spirit. Identify the peaks by their retention times. Measure their areas (or heights) to calculate the concentrations by the external standard method. Take into account any dilutions made to the sample.
The final result is the sum of sucrose, maltose, lactose, glucose and fructose, expressed as invert sugar in g/l.
Invert sugar is calculated as the sum of all monosaccharides and reducing disaccharides present, plus the stoichiometric amount of glucose and fructose calculated from the sucrose present.
Invert sugar (g/l) glucose (g/l) + fructose (g/l) + maltose (g/l) + lactose (g/l) + (sucrose (g/l) × 1,05).
1,05 (molecular weight of fructose + molecular weight of glucose)/molecular weight of sucrose.
